The power LED and the fuse indicator lights on both my differential receiver board and my F8 distro board are blinking when I apply power. I have checked the wiring and, assuming the terminals are labeled correctly, V+ and GND are wired correctly. I assume blinking lights are a bad thing. I have not ruled out the possibility that I have a gimpy PSU. Or are the blinking lights a feature?

ETA: I have nothing connected to either board yet. Wanted to ensure good power up before adding anything.

I either have five bad PSUs or the ones Ray sent me are EU rather than US voltage. His spec says 120/230v supply, but there's no select switch on them. I put a multimeter on the PSU outputs and the output voltage ramps from 1v to 10v in 2v-ish increments then falls back down to one. They continue cycling thusly. So I'm thinking they won't run off 110/120v.
